From an IT governance perspective, which of the following would be the MOST significant impact of moving all IT applications to an external Software as a Service (SaaS) cloud provider?

While the integration of IT with business lines is always important, moving to SaaS doesn't inherently change this integration; rather, it changes how IT fulfills its part of the integration through external services.

When an enterprise moves all IT applications to an external SaaS provider, the internal IT department no longer directly delivers the application services but rather manages the relationship, performance, and compliance of the external vendor. This fundamentally changes the IT governance role, emphasizing vendor management, contract negotiation, service level agreement (SLA) monitoring, and integration oversight.

The improvement of IT service alignment with business is an objective that can be enabled by SaaS, but it's not the primary or most significant *impact* on IT governance itself, which is about how IT is managed.

The necessity to update key risk indicators (KRIs) is a consequence of shifting to SaaS due to new external risks, but it is a specific adjustment within governance rather than the most significant overarching shift in the governance model itself.
